Training metrics displayed via Strava. Distances, paces, and elevation are captured in real time as this marathon block progresses

Current Training Block

Every run in this build-up is visible here — long runs, tempo efforts, and easy recovery days. Distances, paces, and elevation changes are tracked in real time, then interpreted alongside fasting and recovery data.
The aim is not heroic volume, but consistent, sustainable stress.

The fasted marathon is not a single event; it is the outcome of months of controlled metabolic and mental training. Weekly running distance and fasting hours are controlled in deliberate steps to see how endurance and metabolic stress interact. The data above shows changes as race day approaches.

Key events such as the 36-hour fasted half-marathon and the 48-hour metabolic shift are marked to track performance after deeper fasting cycles.

Recovery and Autonomic Signals

Measuring HRV and Resting Heart Rate Trends

Heart rate variability and resting heart rate are tracked daily through Fitbit to monitor how the nervous system responds to training and fasting.

Stable or improving HRV with a gradual decline in resting heart rate suggests adaptation, not overload. Sharp drops or unexplained spikes trigger changes in fasting windows, training intensity, or sleep priorities.

Sleep and Readiness

Average for last 14 days

Sleep duration and timing are recorded every night.

The goal is not perfection, but enough deep and REM sleep to support decision-making, training, and travel.

If sleep quality or duration falls for several days, the protocol shifts toward recovery, not additional stress.

Key Milestones in the Fasted Marathon Build-Up

Each major effort in this journey functions as a checkpoint — a way to test whether the system is ready to progress.

Tools Powering This Experiment

When something meaningful happens in this experiment — a major long run, a new fasting protocol, or race-day results — I document it in a concise brief. No daily noise, just structured updates and what the data suggests for long-term performance and health.

    Integrate Your Technology or Brand

    If your brand develops tools for metabolic health, wearables, recovery, or executive performance, this fasted marathon project is a live testbed. Protocols are pre-planned, data is collected consistently, and results are published openly.

    Partners can position their products inside a real-world executive experiment — not a controlled lab or one-off campaign.
